Description
Technical field
The present invention relates to gangue process field, in particular to a kind of control methods of gangue spontaneous combustion.
Background technique
Gangue is the solid waste of discharge during coal mining and dressing of coal by washing, a large amount of due to containing in spoil
The rush such as pyrite and coal fire combustible, are accumulated for a long time, spontaneous combustion often occur in the case where environmental condition is suitable for, and produce
The toxic and harmful gas such as raw a large amount of SO2, CO, H2S, CO2, seriously affect the environment in mining area and the safety of people's lives and properties.
The prior art is big to the processing one side control expense of gangue, on the other hand generates secondary pollution, and success rate to environment
It is low, it on the other hand not can effectively solve surface strength and soda acid erosion problem, cannot effectively completely cut off air, the gangues such as rainwater are certainly
The necessary condition of combustion.
Summary of the invention
The technical problem to be solved by the present invention is to gangue spontaneous combustion can be effectively prevent by providing one kind in view of the above problems
Method.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of control method of gangue spontaneous combustion, packet
Include following steps:
1. removing the combustible in gangue；
2. gangue+flyash+efficient the flyash excitant of carbide slag+independent research, is proportionally mixed；
It is placed 3. stirring evenly, is fabricated to coal gangue concrete；
4. carrying out building for template, poured after the completion of building with coal gangue concrete；
5. carrying out placement layer by layer as needed, reinforcing bar is assigned to carry out the fixation between each layer between every layer；
6. being laid with geotextiles carries out reinforcing wall；
7. pair building built carries out shape beautification, such as moulding and greening.
The advantages of the present invention over the prior art are that: the gangue+flyash+efficient fine coal of carbide slag+independent research
Grey exciting agent, synthesizing new environmental protection non-reinforced concrete intensity is high, and anti-soda acid corrodes, and can effectively completely cut off air, the gangues such as rainwater
The necessary condition of spontaneous combustion carries out cofferdam to existing gangue slag muck using gangue environmental protection non-reinforced concrete, covers, moulding is green
The problems such as change etc., the thoroughly spontaneous combustion of solution gangue, fugitive dust, while science solves flyash, the Industrial Solid Wastes such as carbide slag
Environmentally friendly handling problems, be truly realized with Industrial Solid Waste administer Industrial Solid Waste, have great significance to China's mine environmental remediation.
As an improvement, the efficient flyash excitant ingredient of independent research is as follows by quality:
Carbide slag 7-11g, saltcake 9-16g, desulfurized gypsum 33-51g, calcium hydroxide 15-22g, sodium hydroxide 6-13g, sulfuric acid
Sodium 12-17g is the ratio of main component synthesizing efficient flyash excitant each component.
As an improvement, the self-service efficient flyash excitant of research and development needs to stand a period of time progress instead after water is added
It answers.
Specific embodiment
The present invention in the specific implementation, a kind of control method of gangue spontaneous combustion, comprising the following steps:
A kind of control method of gangue spontaneous combustion, comprising the following steps:
1. removing the combustible in gangue；
2. gangue+flyash+efficient the flyash excitant of carbide slag+independent research, is proportionally mixed；
It is placed 3. stirring evenly, is fabricated to coal gangue concrete；
4. carrying out building for template, poured after the completion of building with coal gangue concrete；
5. carrying out placement layer by layer as needed, reinforcing bar is assigned to carry out the fixation between each layer between every layer；
6. being laid with geotextiles carries out reinforcing wall；
7. pair building built carries out shape beautification, such as moulding and greening.
Effectively mining slag can be recycled, save a large amount of material resources and waste disposal expense, by work
Industry waste material is transformed into the building of progress protective construction after available resources, kills two birds with one stone, and saves the functional work such as cofferdam
The problem of waste of resource of Cheng Jianzhu.
The efficient flyash excitant ingredient of independent research is as follows by quality:
Carbide slag 7-11g, desulfurized gypsum 33-51g, calcium hydroxide 15-22g, sodium hydroxide 6-13g, sodium sulphate 12-17g are
The ratio of main component synthesizing efficient flyash excitant each component.
It needs to stand after the efficient flyash excitant addition water of self-service research and development and be reacted for a period of time.
Using coal gangue as raw material, it gathers materials on the spot, gangue is administered at site operation, scene, during improving mine environment, no
Secondary pollution is generated, does not consume any resource.Gangue+flyash+efficient the flyash excitant of carbide slag+independent research closes
High at novel environment friendly non-reinforced concrete intensity, anti-soda acid corrodes, and can effectively completely cut off air, the necessary item of the gangues spontaneous combustion such as rainwater
Part carries out cofferdam, covering, moulding, greening etc., thoroughly solution to existing gangue slag muck using gangue environmental protection non-reinforced concrete
The problems such as spontaneous combustion of gangue, fugitive dust, improves mining area ecological environment.
Calcium carbide waste slag cement has the enterprise of numerous maturations at home, and proprietary cement producing line digestion calcium carbide is useless
Slag.Slurry concentration is concentrated to by 5%-8% by 35%, sand pump using concentration basin and is sent into hopper, after point removing a part of supernatant
It is configured to cement slurry with sandstone, clay slip, then send calcined by rotary kiln cement.The differentiation of desulfurization gypsum powder and general land plaster
Be, desulfurization gypsum powder has renewable, and granularity is small, stable components, and objectionable impurities content is few, it is with high purity the features such as, more ring
It protects, it is ensured that the gelatification of gypsum, main material of the calcium hydroxide as concrete, when sodium hydroxide accelerates to chemically react
Between, sodium sulphate is used for reinforcing after concrete setting, and the selection of entire concrete material is more environmentally-friendly, and use is all adopted
Ore wastes, reproduction after being mixed avoid expense and labour consumed by waste disposal, also reduce the row of pollutant
It puts, the effect of environmental protection can be played.
